Updated gcc to 3.1 (rpm gcc-3.1-2) and stock RH kernel 2.4.18-0.26. Rebuilt the
kernel with gcc. Kernel is loading and working OK.
But vmware 3.1 kernel modules crash the system (kernel OOPs). Even after running
vmware-config.pl... With gcc 2.96 everything was OK. Is gcc 3 supported as
kernel compiler by RH?

I don't think we officially support gcc 3.x for anything (at least without a
special GCC support contract). For kernels you'd want the latest kernel at
least, and even if the kernel would work, it's unsure if the vmware modules are
gcc 3.x ready.
One thing you should never ever do: mix 2.96 and 3.x gcc's kernel wise. With
that I mean for example compiling the vmlinuz with 3.x and modules with 2.96 or
the other way around. All should be compiled with the EXACT same gcc.

We haven't tested the 7.3 kernel with gcc 3; so I expect that the first release
using gcc 3.x would be the first one where we do. No comment about version
numbers for that release.
I'll close this bug as "defered" since it's for some next release
